APPLICATIONS

Dedicated to Sub-Bass applications when high power handling

is not specified, these drivers are able to cover a wide frequency

band, ranging from 30Hz to 500Hz with remarkable sonic

properties (even considering directivity pattern) that allow them

to be used in a three-way Sound Reinforcement system as well as

in a specific Sub system of medium input power.

The recommended enclosure is a Reflex type with volume ranging

from 200L to 250L tuned from 38Hz to 40 Hz.

FEATURES

Power handling capacity 500 W AES

Reference efficiency(1W @ 1m) 98 dB SPL

SPL max (continuous) 121dB SPL

Usable frequency range 30-1200 Hz

Environmental withstanding Outdoor

DESIGN CONCEPT

DEFLECTION CONTROLLED DIAPHRAGM optimized for dynamic

damping. DEFLECTION CONTROLLED DIAPHRAGM technology

consists in optimizing the shape and material of the diaphragm so

that it works as a mechanical transmission line, to avoid breaking

modes as well as mechanical threshold which destroy sound

quality.

This leading edge technology offers substantial sonic advantages.

Among them: sound coherency, fast transients, stable sound

imaging, high sensitivity, wide frequency range and reduced

directivity pattern.

VENTED COMPACT MAGNET SYSTEM. It has been carefully

optimized to obtain maximum transducing efficiency while

avoiding unlinear behavior such as coil inductance variation with

position, flux modulation, harmonic distortion, rest position offset,

air compression and off-axis voice-coil pushing.

Its design incorporates a T-shaped and vented pole piece, and

a flux stabilization ring. It also takes into consideration

demagnetization at cold temperatures.

INTERCOOLER SYSTEM (patented). Entirely integrated into the

loudspeaker itself, the INTERCOOLER SYSTEM extracts the heat

produced by Joule effect in the voice-coil by the means of an air

flow directed through the heatsink rims of the basket by the

motion of the dust-cap and the spider.

The gain brought about by this technology is over 20 % of extra

power, so for example, a 3”coil according to this design has

the same power handling capacity as a classical 4”one.

PHYSICAL CHARACTERISTICS

PHL Audio S.A. provides these specifications as representative of current production after conditioning. Because of our continuous research, they are subject to change without notice.

SPECIFICATION NOTES

Note 1 : Allowing for energy response, excursion

capability, Power spectrum, and -3dB low

freq. roll-off for standard reflex tuning.

Note 2 : Established at 20°C ambient temp, according to

AES2-1984 standard using IEC268-1 simulated

programme signal and a 150 liter Bass-Reflex test
